The battery critical functions such as State-of-Charge (SoC) and State-of-Health (SoH) estimations, over-current, and over-/under-voltage protections mainly depend on current and voltage sensor measurements. Therefore, it is imperative to develop a reliable sensor fault diagnosis scheme to guarantee the battery performance, safety and life. This paper presents a systematic model-based fault dia...

This paper proposes the use of bridge type fault current limiters (BFCLs) as a potential solution to reduce the impact of fault disturbance on voltage source converter-based high voltage DC (VSC-HVDC) systems. Since VSC-HVDC systems are vulnerable to faults, it is essential to enhance the fault ride-through (FRT) capability with auxiliary control devices like BFCLs. BFCL controllers have been d...

Günümüzde, nüfus artışı, yerleşim yerlerinin ve endüstriyel alanların genişlemesi teknolojinin gelişmesiyle birlikte elektrik tüketiminde önemli bir artış görülmektedir. Buna paralel olarak üretim kapasitelerinin de artması ile güç sistemlerinde çeşitli sebeplerle meydana gelen arızaların sebep olduğu yüksek akım seviyeleri, sistemdeki elemanlar için tehlikeli durumlar oluşturmaktadır. Arıza ak...

Artificial intelligence algorithms and vibration signature monitoring are recurrent approaches to perform early bearing damage identification in induction motors. This approach is unfeasible most industrial applications because these machines unable their nominal functions under damaged conditions. In addition, many installed at inaccessible sites or housing prevents the setting of new sensors....

The turn-to-turn short is one major fault of the motor faults of BLDC motors and can appear frequently. When the fault happens, the motor can be operated without breakdown, but it is necessary to maintain the motor for continuous working. In past research, several methods have been applied to detect winding faults. The representative approaches have been focusing on current signals, which can g...

All of the induction motor faults are not detect in beginning and late perception of these faults will cause to very lose tolerance. Thus, fault detection and identification in induction motors have high importance for industrial activities. One of the most fault detection methods is motor current signal analysis. In this paper, we use a new method with title induction motor stator current sign...
